SPECIFICATION forming part of Letters Patent No. 653,324, dated July 10, 1900.

Application filed September 27, 1899. Serial No. 731,861. (No model.)

To all whom it may concern.-

Be itknown that I, GUSTAVUS L. STUEBNER, a citizen of the United States, and a resident of the borough of Queens, New York city, in the county of Queens and State of New York, have invented certain new and useful Improvements in Bucket Oonveyers, of which the following is a specification.

This invention relates to improvements in bucket conveyers, and has for its object a conveyer in which buckets suspended from drivechains operate with novel filling and dumping devices. The wheels and tracks ordinarily used with conveyer-buckets'are dispensed with. i

To these ends my conveyer consists of the construction and combination of parts, all as hereinafter shown in the drawings, described in the specification, and pointed out in the claims.

Figure 1 represents an elevation of my conveyer, showing its application in conveying coal from cars to coal-pockets. Fig. 2 shows an end View ofFig. 1. Fig. 3 represents an elevation of the filler, with a few of the buckets and the drive-chains shown in outline. Fig. et is a plan of the filler. Figs. 5 and 6 are end views of Fig. 3. I Fig. 7 represents an ele vation of the dumping device, with a few of the buckets and the drive-chains in outline. Fig. 8 shows a plan of Fig.7. Figs. 9 and 10 are end views of Fig. 7. Fig.11 shows an end view of the drive-Wheels with a portion of the drive-chains and a bucket. Fig. 12 shows a side view of Fig. 11. Fig. 13 represents aplan view of one of the drive-wheels. Fig. 14 is a' fragmentary. vertical section of one of the drive-chains and one ofgthe bucket-hangers, taken on lines a e e e of Fig. 12,and a portion of one bucket. Fig. 15 shows an end View of the sheaves F with one of the buckets and the drive-chains in section on the line 2 z of Fig. 16. Fig. 16 is a front view'of Fig. 15. Fig. 17 shows an elevation of the guide-truck; Fig. 18 is a side view ofFig. 17. Figs. 19 and 20 show a side and front view of the railclainps.

Referring to Figs. 1 and 2, my conveyer is shown to essentially consist of the buckets A,

the drive-chains B, the filler C, the dumping device D ,the drive-wheels E,the guide-sheaves F F F F F and the guide-truck G. The

drawings show the adaptation of my conveyor for conveying coal from cars H'I-I to coal-pockets I. The coal-cars are shown on tracks H, supported on a trestle which runs parallel to the length of the structure constituting the coal-pockets. The trestle is of sufficient height to allow a proper pitch t-o be given to the'chutes h, which lead the coal to the fillers 0, located outside of the longitudinal run of the trestle, this disposition or its equivalent being necessary to allow room for the buckets when rising to and lowering from the top of the coal-pockets I. The arrangement also allows the emptying of all the coal-cars by .means of the tiller 0 without the necessity of moving the train of coal-cars after being placed in position, the filler 0 being moved on the tracks 0 to connect with the different chutes h under the cars. Rail-clamps secure the filler in operative posit-ion. On the top of the coal-pockets I tracks I are placed for the guide-truck G, which is also clamped in any suitable position on the track. Its office is to avoid too great a sag in the drive-chains, and thus prevent the buckets striking the roof of the coal-pockets when in operation. Similar guide-trucks are also at times placed on the tracks 0 for a similar purpose.

The conveyer' is operated by the rotation of the sprocket drive-wheels E, which propel the drive-chains B, to which the buckets A are attached, the direction'of the motion being indicated by the arrows. The drivewheels are driven by any suitable source of power. The coal is deposited intothe filler C from the coal-cars H H through the chutes h, the supply being regulated by cut-offs h.

Referring. to Figs. 3 to 6, the filler O is shown to consist of the box 0, withthe vertical sides I), a curved end at a, and open at the end d. The bottom is raised with the smooth curve ate, and one ol the sides is formed into a chute I), through which the coal enters the filler. The box 0 is supported on theside sills ff, which are joined by the cross-ties g g g. Short lengths of channels i i are fastened to the sills ff, with which they form bearings for the journal-boxes 70 70 lot the axles Z Z, with which the wheels m m turn. Stanchions r carry the guide-rollers r, and stanchions p p carry the guide-barrels p p. The guide-rollers r 0" turn on pins r thetrack when in operative position.

in supports and the guide-barrels p 19' turn on axles p in journal-boxes 19 A T- rail 15 secures the plates 25" t to prevent the buckets rising between the guide-barrels p p. Gross-ties o o and diagonal ties r r and p p are added to secure stability. The railclamps M secure the filler in operative position. 1

Referring to Figs. 7 to 10, the dumping device D is shown to essentially consist of the guide-rollers 1 1, turning on axle 4 in the supports 3 3, secured on the stanchions 2 2, which are suitably connected to the sills 5 of the truck. A chute 6 is supported on angles 9 and 10 and is framed with the runways 7 by means of the braces 28 and 29. The runways 7, which are generally made of angleiron, are curved over the axle 4 and are connected by a tie 22. Over the runways 7 the guides 8 are secured, attaching the same to the ties 18 and 26, which latter is held by the ties 21. Short lengths of channels 23 are fastened to the side sills 5 5, by means of which bearings are secured for the journal-boxes 24, in which the axles of the wheels 11 turn. The rail-clamps M hold the truck in place on The stanchions 12 carry the supports 13, with pins 14, which carry the guide-roller 15. Crossangles 16 carry the plate 17. The cross-tie 27 ties the stanchions 12 and the cross-tie 18 ties the stanchions 2 2. Diagonal ties are shown at 19 and'20.

Refer-ring to Figs. 11 to 14, the drive-chains B are shown to consist of the double links 12 b and the single links 11 connected by pins 12 the pins having heads b collars Z), and split pins 12 The double links 12 fit over the teeth 6 of the drive-wheels E. The bucket A is shown suspended from the drive-chain B B by means of the hangers a which hang from the bolt 0%, which is turned down at a to enter the hangers a a and then is secured by the single links 19 of the drive-chains. Collars b, with split pins b hold the bolts in place. the same form, one pair of which is shown in Figs. 15 and 16, which also show one of the buckets and a portion of the drivechains, the latter being shown in section in Fig. 15 on the line a z of Fig. 16.

Referring to Figs.17 and 18, the guide-truck consists of the guide rollers 9 carried by the supports 9 and pins g on the stanchions The stanchions g with the ties g are secured to the sills g, which are connected by the ties 9 The j ournal-boxes g? support the axles 9 and the wheels g.

Referring to Figs. 19 to 20,- the rail-clamps consist of the hanger 30, riveted to the angle 31, which is fastened to the side sill of the car and also to the angle 32. It is curved over the head of'the rail, as at 33, and a link 34 is iournaled to the hanger 33 by the pin 35. When the nut 36 of the bolt 37 is tightened up, the clamp is secured to the track-rail and the car is held in operative position.-

ets is caught in this chute.

The guide-sheaves F to F are all of When operating my conveyer, the coal is broughtin cars H and dumped into the chutes h, where the cut-offs h regulate the amount admitted to the filler C. When the buckets A enter the filler C, (see Fig. 3,) the side of the, buckets, as a, strikes the curved portion 6' of the bottom of the filler, and while the buckets are being driven by the drive-chains through the filler they are tipped and take the positions indicated at A A A A When the buckets pass under the guide-barrels p'p and plates t 26, they are prevented from rising, and as they are forced through the filler by the drive-chains they must be charged with coal.

When the drive-chains carry the buckets over the guide-rollers n n, the disposition of the rollers and left-hand guide-barrel p is such that the buckets will be tipped, as shown, in position A by which the bucket is prevented from receiving too great a charge of coal, the overload falling out of the bucket and back into the filler. As the buckets leave the filler they are driven to the guidesheaves F Fig. 1, from which they rise vertically, as shown, until they reach the guidesheaves F from which they run horizontally to the dumping device D. When the buckets enter the dumping device, (see Fig. 7,)

the sides of the buckets, as a, strike the curved tie 22 over the axle 4, and by the directions taken by the drive-chains assume positions as shown. The buckets descend on the runways 7, which are generally made of angle-iron, and the guides 8 prevent the buckets from turning over while sliding down the said runways 7. The chute 6 is placed below 7 and all the coal dumped by the buck The axle 4 is placed beyond and in this case to the left and above the end of the chute, so that when the bucket begins to tip over the axle 4 it is over the chute 6 and the coal is prevented from spilling and it all falls into the chute 6 and from there into the openings 00 w w (see Fig. 1) on top of the coal pockets.

Having described my invention, I desire to secure by United States Letters Patent and claim- 1. A filler comprising a box open at one end, with vertical sides and a curved front,

a chute formed in one of the sides thereof and a bottom with a portion thereof raised with a smooth curve; a suitable frame; truckwheels; guide-barrels and guide-sheavessupported on the frame, and rail-clarnps substantially as described.

2. A dumping device comprising a platform; truck-wheels carrying said platform; stanchions mounted on the platform; braces connecting thestanchions; an axle secured by means of supports to two opposite stanchions on the bucket-entering end of the platform; two guide-rollers turning on said axle; inclined runways curved over and supported at their upper ends on said axle, and

at their lower ends connected to the platform by a cross-brace3 inclined guides parallel to turning the buckets; a chute under the dumping device; a guidetruck for the drivechains; sprocket drive-whee1s; guide-sheaves; guide-barrels; cut-offs for regulating the supply of material to be conveyed to the filler, all substantially as described.
